🦴 What Is an Anatomic Total Shoulder Replacement?
An anatomic total shoulder replacement (aTSA) involves replacing the damaged ball-and-socket joint of the shoulder with prosthetic components that replicate the shoulder’s natural structure. The surgery is typically performed to relieve pain and restore function in people with:
- Osteoarthritis
- Post-traumatic arthritis
- Avascular necrosis
- Intact or repairable rotator cuff tendons
Unlike a reverse shoulder replacement, aTSA relies on healthy rotator cuff muscles to control movement and stabilise the joint.
🩺 Before Surgery: How to Prepare
✅ Understand the Procedure
The procedure involves:
- Replacing the humeral head (ball) with a metal component
- Replacing the glenoid socket with a polyethylene or metal-backed implant
You’ll typically stay in hospital for 1–2 nights and begin physiotherapy soon after.
✅ Pre-Surgical Physiotherapy (Prehab)
Prehab helps set you up for a smoother recovery and has been shown to:
- Improve confidence with sling use and post-op exercises
- Reduce early stiffness and pain
- Support faster return to daily activities
Your physio will focus on:
- Gentle shoulder mobility
- Strengthening scapular and postural muscles
- Teaching early rehab exercises
- Advising on sleep, pacing, and home setup
“Pre-operative physiotherapy can shorten hospital stays and improve early functional recovery.” — Moreside et al., 2019
✅ Set Up Your Home Environment
- Prepare a recliner or wedge pillow system for semi-upright sleeping
- Organise transport, meals, and personal care support
- Stock up on essentials—especially items that don’t require lifting or reaching
- Plan to wear a sling full-time for at least 4–6 weeks
🛌 Sleeping After Shoulder Replacement
Getting restful sleep can be a challenge post-op. Try the following:
- Sleep semi-reclined in a chair or propped up in bed (30–45° incline)
- Use a pillow or towel roll under the elbow to support the arm
- Keep the sling on at night unless your surgeon advises otherwise
- Avoid lying flat or on your side for the first several weeks
Tip: Practice your sleeping setup during the day so you’re prepared for night one.
📆 Recovery Timeline: What to Expect Week by Week
| Phase | Timeline | Key Goals |
|---|---|---|
| Protection | Weeks 0–2 | Pain relief, healing, passive range of motion only |
| Mobilisation | Weeks 3–6 | Active-assisted ROM, start scapular control |
| Functional use | Weeks 6–12 | Begin active ROM, resume light daily activities |
| Strengthening | 3–6 months | Progressive resistance, restore function |
| Return to full activity | 6–12 months | Build endurance, sport/task-specific rehab |
🏋🏻♂️ General Lifting Timeline
| Timeline | Lifting Ability |
|---|---|
| 0–6 weeks | No lifting with operated arm |
| 6–12 weeks | Light object handling (cutlery, remote), <1 kg |
| 3–4 months | Gradual return to 1–3 kg (e.g. light bags) |
| 4–6 months | Moderate household loads (~5 kg) |
| 6+ months | Heavier lifting as guided by physio/surgeon |
Always check with your surgeon and physiotherapist before increasing load.
🏌🏼♀️ Returning to Daily Activities and Sports
| Activity | Timeline Estimate |
|---|---|
| Driving | 6–8 weeks |
| Desk work | 2–4 weeks |
| Light housework | 6–12 weeks |
| Swimming/Golf | 4–6 months |
| Resistance Training | 3–5 months |
| Contact sports | ❌ Not recommended |
Contact sports are generally avoided due to the high risk of dislocation or implant damage. In rare cases, return to modified low-contact activity may be considered under close supervision.
⚠️ Stiffness After Surgery: Why Early Rehab Matters
Some patients develop limited shoulder motion during recovery. This often results from:
- Pre-existing stiffness
- Prolonged immobilisation
- Pain-avoidance or guarded movement
Early physiotherapy is crucial to help maintain movement, reduce pain, and prevent long-term limitations. A proactive rehab plan is one of the most effective ways to reduce this risk.
⚠️ Nerve Injury: Rare but Important to Know
Nerve irritation after shoulder replacement is uncommon (1–3%), but possible. It may occur from surgical stretch or retraction and most often affects:
- The axillary nerve (numbness/weakness over the shoulder)
- The suprascapular nerve (difficulty lifting arm)
- The radial nerve (rare—wrist/finger weakness)
Most cases resolve over weeks to months with conservative care and physiotherapy. Severe or prolonged symptoms may need specialist review.
🧑⚕️ How Physiotherapy Supports Recovery
Physiotherapy is essential at every stage of shoulder replacement recovery. Your physiotherapist will:
- Guide you through each stage of rehab
- Prevent compensations and stiffness
- Restore safe strength and control
- Support return to daily life, work, and sport
We individualise rehab based on your goals and surgeon’s protocol, ensuring the best outcome over the long term.
✅ What Can You Realistically Expect?
- Most patients experience significant pain relief
- Daily activities become easier and more comfortable
- Some residual stiffness or strength limitation is normal
- Long-term implant success depends on surgical technique, rehab, and load management
