Introduction: shoulder surgery in the face of the opioid crisis

Shoulder surgery occupies a singular place within the orthopedic armamentarium. Rotator cuff repair, anterior stabilization (Latarjet procedure), subacromial decompression, anatomical or reverse arthroplasty: these interventions share a common denominator, intense post-operative pain, often with nocturnal exacerbation, and a prolonged period of immobilization with a sling or orthosis. This combination makes shoulder surgery one of the highest outpatient consumers of opioids.

Yet the epidemiological context has shifted. The opioid crisis, identified in North America from the late 2010s onwards and now monitored across most Western and Gulf healthcare systems, has placed orthopedic surgeons under particular scrutiny. Orthopedic surgeons are among the heaviest prescribers of post-operative opioids, and the risk of transition from acute use to chronic dependence in opioid-naïve patients is now well documented. Institutional recommendations, in North America as well as in the United Arab Emirates, converge: reduce prescribing, multiply multimodal approaches, integrate validated non-pharmacological modalities.

It is in this context that the 2024 publication of the multicenter randomized trial by Khan et al. (AOSSM 2024 Annual Meeting / The Orthopaedic Journal of Sports Medicine) takes on particular significance. This trial quantifies, for the first time across 200 patients in 5 hospitals, the reduction in opioid consumption attributable to cryocompression after shoulder surgery. This article presents its methodology, detailed results and concrete clinical implications for post-operative management in the MENA region.

Specifics of post-operative pain in shoulder surgery

Anatomy and type of intervention

The glenohumeral joint is the most mobile in the human body, which makes it both a frequent surgical target and an area particularly sensitive in the post-operative period. The most common procedures are:

• Rotator cuff repair (mainly supraspinatus): transosseous or single/double-row suture, in a richly innervated area, requiring 4 to 6 weeks of immobilization.
• Latarjet procedure: coracoid transfer for recurrent anterior instability, a bony procedure with painful and prolonged post-operative course.
• Shoulder arthroplasty (anatomical or reverse): more invasive interventions in often elderly patients, with delicate pain management.
• Subacromial decompression, biceps tenodesis, arthroscopic capsulorrhaphy: arthroscopic procedures with non-negligible residual swelling and pain.

The challenge of nocturnal pain

One feature distinguishes shoulder surgery from other orthopedic interventions: nocturnal pain. The supine position, loss of the gravitational support provided by upright posture, the absence of distraction and reduced neurosensory tolerance at night all combine to amplify the perception of pain. This nocturnal pain leads to sleep disturbances, which in turn worsen daytime pain perception and compromise overall recovery.

It is precisely during these first nights that the temptation to take opioids is strongest, and it is in this window that any modality capable of reducing pain without central sedative effect proves immediately useful.

The inflammatory cascade and the interscalene block

Most elective shoulder procedures benefit from a peri-operative interscalene block providing effective analgesia for 12 to 24 hours. But once the block wears off, typically the night following the procedure, pain returns sharply, sometimes with a rebound effect. This is what surgeons and anesthesiologists refer to as “rebound pain”: a pain spike between the 12th and 24th hour, occurring exactly when the patient has returned home and most often has only opioid tablets at their disposal. Home-based cryocompression, initiated upon return, aims precisely to attenuate this peak.

Mechanisms: why cryocompression acts on shoulder pain

Controlled cold

The application of controlled cold at 4°C exerts three concurrent actions:

• Vasoconstriction of subcutaneous and superficial muscular planes, limiting extravasation and peri-articular swelling.
• Slowing of peripheral nerve conduction, particularly on the Aδ and C fibers carrying acute nociception.
• Reduction of local cellular metabolism, attenuating the release of pro-inflammatory mediators.

Unlike a conventional ice pack, the maintenance of a stable temperature between 2 and 10°C, without extreme variation, allows prolonged exposure without risk of frostbite and a sustained analgesic effect.

Dynamic intermittent compression

The shoulder presents a particular anatomical challenge: its convex shape and the presence of bony prominences (acromion, coracoid process) make it difficult to apply a homogeneous static compression sleeve. Dynamic intermittent compression, modulated between 5 and 75 mmHg, offers several advantages:

• It mobilizes peri-articular swelling toward the cervical and axillary lymphatic chains.
• It conforms the cold sleeve to the anatomical contours, optimizing thermal transfer.
• It prevents stasis in the muscle compartments immobilized by the sling.

The cryo + compression synergy

The combination produces an effect greater than the sum of its parts. Mechanical pressure brings the cold source closer to the deep planes while promoting drainage, while cold limits reactive vasodilation. Controlled cold at 4°C combined with dynamic intermittent compression thus constitutes a tool consistent with the post-operative pathophysiology of the shoulder.

Clinical evidence: the Khan et al. 2024 trial

Study design

The landmark study published by Khan M, Phillips S, Mathew P, Venkateswaran V, Haverstock J, Dagher D, Yardley D, Dick D, Bhandari M. in 2024 is to date the most robust work on the question of opioids after shoulder surgery and cryocompression.

Detailed results

Primary endpoint, opioid consumption

Median opioid consumption was:

• 56.1 OMME [IQR 66.1] in the cryocompression group (Game Ready)
• 112 OMME [IQR 99.4] in the standard cryotherapy group
• p = 0.02468, statistically significant

This corresponds to an approximately 50% reduction in median opioid consumption. At the individual patient level, this decrease concretely represents half of the cumulative opioid dose consumed during the acute post-operative phase. At the department level, across a typical annual volume of shoulder surgery, the potential savings in morphine equivalents is considerable.

Secondary endpoint, physical function

Physical function evaluated by SF-36 at 2 weeks post-operatively showed:

• 61.2 ± 21.2 in the cryocompression group
• 54.2 ± 22.9 in the control group
• p = 0.0412, significant

This improvement suggests that the reduction in opioids is not accompanied solely by lower medication intake, but by a better functional level at two weeks, meaning a qualitatively superior recovery in the window when rehabilitation begins.

Secondary endpoints, other

• Time to opioid cessation: median 4 days (cryocompression) vs. 6 days (control), non-significant difference (p = 0.1543).
• VAS pain score: no statistically significant difference between the two groups. This point is crucial to interpret: cryocompression does not measurably lower the VAS but allows equivalent levels of pain to be achieved with half as many opioids.
• Adverse events: 4 in the cryocompression group, 2 in the control group, non-significant difference and without severity.

Clinical interpretation

The major lesson from the Khan 2024 trial is not that cryocompression eliminates pain. It is that it allows for partial opioid substitution: at an equivalent level of perceived pain, the patient takes half as many opioid analgesics. Within a framework of multimodal analgesia and prevention of dependence, this substitution is exactly the effect sought.

The concurrent improvement in SF-36 at 2 weeks confirms the absence of a detrimental effect on functional recovery, and even suggests a net benefit on the quality of early rehabilitation.

Complementary 2015 study

A randomized study published in 2015 (PMID: 25825138) evaluated cryocompression versus standard ice after rotator cuff repair in 46 patients.

While the study did not show a significant difference in total morphine consumption, it did demonstrate better sleep on the night following the procedure in the cryocompression group, confirming the particular value of this modality in managing post-shoulder nocturnal pain. The modest sample size limits the statistical reach, but the signal is consistent with Khan 2024.

Synthesis

Recent data confirm measurable benefits on opioid consumption, early physical function and post-operative sleep, with no unfavorable safety signal. For a procedure in which nocturnal pain and opioid consumption are the two main pitfalls of the first month, these results position cryocompression as a leading modality within a multimodal strategy.

Clinical implications: practical post-shoulder-surgery protocol

Timing

Initiation of cryocompression as soon as the patient returns home, either on the evening of outpatient surgery, or the following morning for patients hospitalized overnight, aims to cover the moment when the interscalene block wears off and the first post-operative night, the period of rebound pain and maximum analgesic demand.

Compatibility with immobilization

The shoulder sleeve is designed to be applied over or under a sling, without compromising immobilization. The patient can put it in place independently once the demonstration has been given. This is an important operational advantage for the first nights when a caregiver may not be present.

Place in the multimodal strategy

Cryocompression fits within a multimodal approach combining:

• peri-operative interscalene block,
• NSAIDs if not contraindicated (to be discussed on a case-by-case basis after rotator cuff repair so as not to compromise healing),
• systematic paracetamol,
• rescue opioids, with regulated dose and duration,
• home cryocompression 4×/day for 7 to 14 days,
• early passive rehabilitation according to the protocol specific to the procedure performed.

Precautions

• Residual insensitivity related to the interscalene block: avoid prolonged sessions until cutaneous sensitivity returns.
• Surgical wounds: waterproof dressing, sleeve over the dressing.
• Frail elderly patients: verify the ability to set up the device and involve the caregiver.

The role of Kolde: bridging the gap between hospital and rehabilitation

The clinical benefit of cryocompression is now quantified. What remains is to make it accessible. In Dubai, many patients are discharged the same day or at D1 after shoulder surgery, begin physiotherapy between D7 and D14, and find themselves during this first week with kitchen ice packs as their only non-pharmacological analgesic tool.

Kolde offers a Dubai-based home rental service for the Game Ready device, designed for the Hospital → Home → Recovery window. The service includes:

• Home delivery in Dubai, generally on the day of surgery or the following morning, to cover the first post-operative night,
• Installation and demonstration of the device and the shoulder sleeve by a trained technician,
• 24/7 support: the first night is the most critical, and Kolde's technical support is reachable at any time,
• Home pickup at the end of the rental, with no need to travel,
• No deposit required.

The durations offered:

Kolde is not a medical device and does not substitute for the surgeon's evaluation. Kolde is a service provider: the decision to use it, the indication, the protocol and cessation remain at the discretion of the prescriber. The objective is to deliver on the Hospital → Home → Recovery promise, that is, the continuity of care between hospital discharge and the first physiotherapy session, precisely the window in which Khan 2024 demonstrates the opioid-sparing effect.

Conclusion: cryocompression, a validated opportunity for opioid sparing

The multicenter randomized trial by Khan et al. 2024 quantifies for the first time, in 200 patients, the impact of cryocompression on opioid consumption after shoulder surgery: median reduction of approximately 50%, significant improvement in physical function at 2 weeks, and preserved safety profile. In a regional and global context where reducing opioid prescribing has become a public health imperative, these results position cryocompression among the most useful modalities of a multimodal post-operative strategy.

For both the surgeon and the physiotherapist, the challenge now shifts toward access to the device at home, as soon as the patient leaves hospital. This is the mission Kolde has set itself in Dubai.
