Why is the first week decisive?
Everything is concentrated in the first days. Oedema, pain and bleeding peak between the 48th and 96th post-operative hour, exactly when mobilisation begins: standing up, walking with an assistive device, first exercises. If inflammation and muscle inhibition are not controlled during this window, rehabilitation starts late and the functional deficit drags on. And since discharge is now early (D1 to D3), this decisive week largely plays out at home, often without an appropriate device.
The post-arthroplasty inflammatory cascade
Hip arthroplasty involves the dissection of deep muscle planes (gluteus medius, tensor fasciae latae, iliopsoas depending on the approach), an osteotomy of the femoral neck, acetabular reaming and the implantation of prosthetic components. This tissue trauma triggers a stereotyped inflammatory cascade: release of pro-inflammatory cytokines, increased capillary permeability, plasma extravasation and the formation of interstitial oedema.
Added to these phenomena is significant post-operative bleeding. THA exposes patients to average blood loss estimated between 800 and 1,500 mL, a large part of which lodges in the muscle compartments of the thigh and gluteal region as diffuse haematomas. These haematomas contribute to pain, to limited range of motion (ROM) and to arthrogenic muscle inhibition.
Anatomical specificities of the hip
Unlike the knee, the hip is a deep joint surrounded by a substantial muscle mass. Two direct consequences follow:
- Surface static cold (an ice pack) struggles to reach the deep articular planes. Thermal diffusion is limited by the thickness of adipose and muscle tissue.
- Lymphatic drainage of the thigh is gravity-dependent and requires active tissue mobilisation. A device delivering dynamic compression reproduces the pumping effect that promotes oedema resorption, where static compression or an ice pack left in place remains passive.
Arthrogenic muscle inhibition (AMI)
AMI refers to the reflex neuromuscular inhibition induced by capsular distension, intra-articular effusion and pain. In practical terms, it translates into a loss of voluntary recruitment of the quadriceps and hip flexors. This inhibition compromises early standing, the quality of walking with an assistive device and, ultimately, delays functional recovery. Reducing oedema and pain in the first post-operative days is therefore a direct lever to limit AMI.
In the hip, the depth of the tissues and the thickness of the muscle make static ice packs largely ineffective on the deep planes. Active dynamic compression is what enables effective thermal transfer and genuine lymphatic drainage.
Mechanisms of action of cryocompression
Cryocompression acts on three complementary levers, where a simple ice pack covers only one.
Less oedema and pain
Vasoconstriction and a slowing of the inflammatory metabolism: less extravasation, less pain, with no systemic effect.
Active oedema drainage
Modulated between 5 and 75 mmHg, it creates a pumping effect that drains interstitial fluid and limits venous stasis.
A deep-reaching action
By bringing the cold closer to the tissues, compression drives it down to the deep planes of the hip, where surface cold remains ineffective.
What do the studies show in THA?
2019 randomised study: thigh oedema and patient satisfaction
A prospective randomised study was conducted in 2019 and published in SICOT-J, the open-access journal of the International Society of Orthopaedic Surgery and Traumatology.1 It evaluated the efficacy of continuous local cryotherapy after THA. Sixty patients were divided into two groups: 30 on continuous local cryotherapy post-operatively, 30 on standard care (control group).
This study demonstrates a measurable benefit on two clinically relevant criteria: the objective reduction of thigh oedema, a direct factor of discomfort and functional limitation, and the patient's subjective perception during the first post-operative week, a period when comfort conditions adherence to early rehabilitation.
2012 study: impact on blood loss
A study published in 2012 in Hip International, a journal specialising in hip surgery, compared 15 sessions of cryocompression of 30 minutes to a simple compression bandage after elective hip arthroplasty.2 The primary endpoint was the drop in haemoglobin at D1: it was markedly lower in the cryocompression group (1.87 mmol/L) than under a simple compression bandage (2.34 mmol/L).
This difference of around 20% in favour of cryocompression suggests a local haemostatic effect, mediated by the cold-induced vasoconstriction and the mechanical pressure applied to the tissue planes.
And after a THA, post-operative anaemia is not just a laboratory figure. Clinically it translates into fatigue, breathlessness on the slightest effort and dizziness when standing up, which delay the return to walking accordingly. Limiting blood loss therefore means a less exhausted patient, a lower transfusion risk and rehabilitation that can start sooner.
What the meta-analyses confirm
These two hip trials are not isolated. Meta-analyses on lower-limb arthroplasty (hip and knee) all point in the same direction on the early post-operative window3, 4: less opioid analgesia, less peri-articular oedema and lower pain scores (VAS) in the short term.
All with a reassuring safety profile: no major adverse event (frostbite, skin lesions) is reported, provided the device is used correctly.
Clinical implications: practical protocol after THA
Timing: the D0–D7 window is critical
Post-operative oedema peaks between 48 and 96 hours after surgery. The value of initiating cryocompression from D0 (theatre discharge) or D1 (at home after early discharge) is to prevent this rise rather than treat it once established. The literature agrees on the first week as the period of maximum benefit.
The protocol in practice
Integration with physiotherapy
Cryocompression does not replace rehabilitation: it makes it possible. Used before and after sessions, it reduces pain and oedema, improves the tolerance of each session and speeds up the progression of range of motion and strength.
Cryocompression is most effective used preventively over the D0–D7 window, applied 4 times a day. It does not replace physiotherapy, it conditions its quality.
Precautions
Skin numbness
In case of persistent epidural anaesthesia, increased monitoring and shorter sessions in the first hours
Surgical wound
Keep a watertight dressing, with the wrap applied over the dressing
Anticoagulation
No contraindication, but monitor superficial haematomas
Textile allergies
Rare, to be reported to the provider before fitting
Kolde's role: bridging the gap between hospital and rehabilitation
For a long time, access to a cryocompression device at home was reserved for hospitals or specialised rehabilitation centres. For the patient discharged at D2 or D3 after a THA, this discontinuity represented an operational gap: available at hospital, unavailable at home, until physiotherapy began.
Kolde is a home rental service for the Game Ready device, designed to address precisely this window.
At the clinic, from Day 0
The device can be set up from the recovery room with an appropriate hip wrap. Kolde also provides direct delivery to the facility on request.
Home return, rental from 1 to 4 weeks
Kolde delivers and installs the Game Ready at the patient's home, generally on the day of discharge or the next day. Installation and demonstration carried out by a trained technician.
Autonomous use at home
30-minute sessions, before and after physiotherapy sessions. Support remains available for any clinical or technical question throughout the rental period.
End of rental and device pickup
At the end of the rental period, Kolde collects the device from the patient's home, with no travel required on their part. No deposit is required.
Conclusion: cryocompression, an emerging standard after THA
The current literature, although still improvable in volume and consistency, converges on several points for cryocompression after THA: objective reduction of thigh oedema, improved patient satisfaction in the first week, a favourable effect on blood loss and an excellent safety profile. Combined with a modern surgical approach, blood-sparing protocols and structured early rehabilitation, it fits fully into enhanced recovery after surgery (ERAS) programmes applied to hip arthroplasty.
For the surgeon as for the physiotherapist, the challenge is now operational: how to guarantee every patient access to this device, at home, as soon as they leave hospital. This is precisely the mission Kolde has set itself.
Cryocompression after total hip arthroplasty reduces thigh oedema, improves patient satisfaction from the first week and limits blood loss, with an excellent safety profile.
These data support its integration into the post-operative recovery pathway, from hospital discharge to the home.
